In biology, Kingdoms are the highest taxonomic groups of living organisms. Biologists since the time of Aristotle (384-322 BC) have divided the living world into two kingdoms, Plants and animals.
The word “plant” suggests grasses, bushes, shrubs, creepers, climbers, vines and trees and “animal” suggests cats, dogs, lions, tigers, birds, frogs and fish.
Further thought brings to mind such forms as ferns, mosses, mushrooms and pond scrums (algae), quite different but recognizable as “plants” and insects, lobsters, clams, worms and snails that are definitely animals
But if you have ever had the pleasure of climbing over the rocky shore of the sea coast, looking at the organisms that cling to the rocks or live in a tide pool, you undoubtedly found some things that were difficult to recognize as animals and plants. The one-celled organisms visible under the microscope cannot easily be assigned to the plant or animal kingdom.
The German biologist Earnst Haeckel (1866) in his book Generelle Morphologie der Organismen suggested a three-kingdom system (Protista, Plantae and Animalia). In the third kingdom Protista he grouped all the single-celled organisms that are intermediate in many respects between plants and animals. Herbert Copeland (1956) have suggested establishing a fourth kingdom, originally called Mycota but later referred to as the Monera, to include the prokaryotes like bacteria and blue-green algae, which have many characteristics is common.
They have a single membrane system without a nucleus, and membrane bounded sub-cellular organelles such as mitochondria or chloroplasts. All other organisms are eukaryotes have a more complex structure with a nucleus and other organelles divided by intracellular membranes. R. H. Whittaker (1969) recognized an additional kingdom for the Fungi. The resulting five- kingdom system suggested by him has received wide acceptance. However, this may not be the end of the story. Some scientists have proposed that organisms be divided into even more (may be as many as 8) kingdoms.
Currently most biologists recognize six kingdoms: two prokaryotic kingdoms (Archaebacteria and Bacteria), a large unicellular eukaryotic kingdom (Protista) and three Multicellular eukaryotic kingdoms (Fungi, Plantae and Animalia). Viruses are not included in any of the present 5 kingdoms – mainly due to their many nonliving characteristics (for example, viruses are not cells).

plants , cell wall is different as animals have cell memberene but plants have cell wall too.
